Specification forming part of Letters Patent No. l94,92 E d ated September 4, 1877; application filed October 26, 1876.

To all 'whom t may concern Be it known that I, BENGT G. LEsTEDT, of Chicago, Cook county, Illinois, have invented a new and useful Improvementin Lan1p- Stoves, which are made substantially as set use of laundries and tailors, and for cooking and other purposes, with the new features hereinafter set forth.

The chamber A is made of sheet metal, to hold the liuid fuel. It has an entrance, E, for filling. This has a securescrew-plug, with a packing-cork, E', inclosed by its outer shell, as shown, to close it, and a guard, N. The chamber A is iilled with cotton-Waste or other brous material to hold the fluid, and to bring the uid into contact with the top shell of the chamber, so as to be vaporized by the heat conducted from the burner.

A hollow column, H, rises from chamber A, and is also filled with fibrous material rising from the chamber below, part way up. lt has a cup, G, around its base, to hold iiuid to heat the stove and burner and start the irc.

The burner is mounted on the top of column H. lt has a solid portion,with a cap, C, below, which screws onto the column H. This solid part has a hole, I, up through it, for the escape of vapor for burning. lt has also a turn-valve, L, through it crosswise, for cutting off or regulating the escape of the vapor and the degree of heat. This valve is conical, so as to iit closely in its seat. The small end has a washer and a screw-nut, by which its tightness-is regulated and wear taken up. This valve has a handle, M, at one side,by which it is operated, the handle extending in frombeyond the vessel-supporting frame.

The passage I opens up into a cage, P. This cage has openings, R, around it, to admit air. The force of the escaping vapor draws the air through these o'penin gs for burning. The stream of mixed vapor Iand air strikes the cap K of the cage, and is spread upward and to the sides for burning.

The quantity ot' heat is regulated, at work, by the valve L, and the quantity of tluid in chamber A by the number of burners and proportions of the parts.

The apparatus is supported by legs F extending below and above chamber A. These support a top frame, F', having a suitable opening up through it for the heat, and placed at a suitable height in relation to the burner. The top frame is made of suitable form to hold the vessels or articles to be heated,and,when

desired, to inclose them, or confine the heat to them eiiicieutly.

I claimv The improved lamp-stove having the tiberlled chamber A with column H, inlet E with cork and screw-plug E and guard N, cup G, and the iron or vessel support F. with legs F, in combination With the turn-valve L, having means for tightening it, and the burner with 'passage I, and cage P having air-inlets R and cap K, substantially as set forth.
